How to run app in debug mode with Flask

Question

I've setup a logger with Flask but it doesn't print to the Pycharm console, thought it might be because of not being in debug mode. app.debug = True but FLASK_DEBUG = 0 when I run the application.

app = Flask(__name__)
app.debug = True

Are you running flask in virtualenv or not? – Abid Khan May 13 '18 at 04:05 — Abid Khan, May 13 '18 at 04:05

Make sure you've acquired the environment variable FLASK_DEBUG in your running environment.

on Unix $ export FLASK_DEBUG=1

on Windows set FLASK_DEBUG=1

Also app.run(debug=False, threaded=True) worked in Python2.6 ... worth a shot.

This also causes your app to restart when changes are detected in the application's source file.

If you are in windows, just use the following code to set flask_debug:

import os
os.environ["FLASK_DEBUG"] = "1"
